Local heating processes are normally adopted to reduce residual stresses in local weld repaired area of spherical vessels,but this procedure itself does cause non-negligible residual thermal stresses.

Non-die explosive forming of spherical vessels is a new technique of the whole forming.

Research on limit load of spherical vessel with elliptical nozzle is conducted through testing the strain and adopting the method of double slope of elastic curve, and the results: minimum limit load of vessel-P=9.
